React NativeRedux Toolkit (RTK): full-featured. RTK Query thay axios cho server state, devtools tốt nhất, time-travel debugging. Phù hợp app lớn (10+ engineers), cần audit trail rõ ràng. Boilerplate vẫn nặng dù RTK đã giảm so với Redux cổ điển. Trên RN, devtools cần Reactotron hoặc Flipper plugin.
Zustand: API tối giản (hook + closure), không context, không boilerplate. Khoảng 1KB bundle. Dễ test (store là plain object). Persist middleware cho RN dùng MMKV/AsyncStorage adapter.
Jotai: atom-based — chia state thành nhiều atom nhỏ, component subscribe atom nào re-render atom đó. Phù hợp UI nhiều nguồn state độc lập (form tự do, canvas).
Khuyến nghị 2026:
- App nhỏ-trung (≤ 50 screen, ≤ 5 dev): Zustand. Đủ tính năng, vô đối về DX.
- App lớn cần audit, time-travel: RTK + RTK Query.
- UI editor/canvas/form đa ngả: Jotai.
- Server state: TanStack Query kèm bất kỳ store nào ở trên cho client state.
Redux Toolkit (RTK): full-featured. RTK Query replaces axios for server state, has the best devtools, and supports time-travel debugging. Fits large apps (10+ engineers) needing a clean audit trail. Boilerplate is still heavy compared with Zustand. On RN, devtools require Reactotron or a Flipper plugin.
Zustand: minimalist API (hook + closure), no context, no boilerplate. ~1 KB bundle. Easy to test (the store is a plain object). The persist middleware works for RN via an MMKV/AsyncStorage adapter.
Jotai: atom-based — split state into small atoms, components subscribe to the atoms they care about. Good fit when UI has many independent state sources (free-form forms, canvas).
Recommendation 2026:
- Small/medium app (≤ 50 screens, ≤ 5 devs): Zustand. Enough features, unbeatable DX.
- Large app needing audit/time-travel: RTK + RTK Query.
- Multi-source editors/canvas/forms: Jotai.
- Server state: TanStack Query alongside any of the above for client state.
